Abstract
A process unit includes a supply unit including a discharge port through which toner is discharged and having a discharge surface around the discharge port, and a reception unit that receives toner from the supply unit. The reception unit includes a reception frame including a reception port for receiving toner from the discharge port, and a reception seal member having a reception seal opening that communicates with the reception port, and a facing surface facing the discharge surface. In a case where the facing surface moves relative to the discharge surface while being in contact with the discharge surface in a state in which the toner exists between the facing surface and the discharge surface, the toner and the discharge surface are charged to a same side polarity relative to a polarity of the facing surface.
